Hours & Events

Because of the wildlife in and around the Arboretum, it's potentially unsafe to visit the site and especially to hike the Sequoia Trail after dark. During daylight hours, that's not an issue.

The booth is open from 11 AM - 3 PM Saturdays and Sundays. We accept cash and Visa or Mastercard, but please note that the minimum credit or debit purchase is $10.

We’re planning to hold the FALL NATIVE PLANT SALE on Saturday, October 14, 9:00 am until we’re sold out. Remember, the line may form as early as 7:30 am.

The Fall newsletter will be coming out soon. 

Adventure Passes

An Adventure Pass or other valid pass (such as America the Beautiful) is required to park in the Arboretum’s lot–whether or not the Information Booth is open. As always, entrance to the Arboretum itself is free.

Paying for an Adventure Pass helps our National Forests. The majority of the fees are used for operating, maintaining and improving recreational opportunities for our visitors.

If our information booth isn’t open, you may purchase an Adventure Pass at:

  • We have a QR Code displayed at the booth which will take you to the Forest Service website where a pass may be purchased online.
  • The 7-11 in Lake Arrowhead, CA 
  • The Lake Arrowhead Chamber of Commerce in Lake Arrowhead Village, Lake Arrowhead, CA
  • Arrowhead Sporting Goods in Lake Arrowhead Village, CA
  • Lake Drive Hardware in Crestline, CA
  • The 7-11 in Crestline, CA
  • Snow Valley Ski Resort in Running Springs, CA
  • Valero in Running Springs, CA
You may also purchase a pass online, but allow for a 2 week delivery time.   https://www.recreation.gov/activitypass/AP21330/order

Semi-Annual Native Plant Sale

Our next  Native Plant Sale will be held on Saturday, October 14, from 9:00 am until all the plants are sold.  The line of shoppers may start forming as early as 7:30 am. The plants will be perfect for getting into the ground immediately, and will bloom in the spring. We sell out of all of our plants within a few hours, so we hope you will come and take advantage of an excellent native-plant selection and support the Arboretum. Plants will be priced from $12 to $15, and the proceeds benefit the Arboretum. The date is dependent on weather conditions that day.

Explore the Forest

This family- and dog-friendly trail is nearly one mile long. Descending and then rising gently, it’s an easy hike with numbered signposts along the way. An information-rich trail guide, keyed to those numeric posts, makes your hike even more interesting and educational.

The Arboretum’s gardens display a wide variety of flowers, shrubs and other plants. Largely native to the San Bernardino Mountains, many of them are identified by easy-to-read signs. The nearby Information Booth offers print and visual aids to help you learn even more!
